A man hijacked a passenger airplane in Cuba this week using two fake hand grenades and ordered it to fly to Key West Florida . It was the second hijacking from Cuba in as many weeks and spawned an argument between the US and Cuban government. US Officials scolded Cuba for incompetent airport security, and Cuba accused the US of being soft on hijackers.

Miami FBI chief Hector Pesquera said in a news conference that the man faces 20 years in federal prison.

Adermis Wilson Gonzalez, 33, boarded the plane with his wife and son and landed in Havana Monday night. The plane was refueled and Cuban government officials held negotiations with the man that eventually led to the release of 20 passengers and the delivery of three white packages to the plane.

It took flight again Tuesday morning and headed to Florida . U.S. fighter jets held defensive positions, but the plane and all 32 people still on board landed safely. Key West International Airport was evacuated.

Wilson was the first off the plane, carrying his son and wearing a red jacket with " America " stitched on the back. The fake grenades were removed from his pockets, and he was arrested. The other passengers were processed by federal agents, but some asked to be allowed to stay in the United States .

Responding to the question of US immigration policy being to blame for such incidents, Philip Reeker, a State Department spokesman, said it is not US law that encourages Cubans to flee their country.

"Our policy, again, is that Cubans should arrive here only through safe, legal and orderly means. So I think it is, again, Cuba that needs to examine the way they treat their people, the way they have for decades, and why their people are so eager to flee their country and seek better opportunities elsewhere, including the United States.
